Growth performance of eel fish (Anguilla bicolor) which are maintained in containers of different colors

Performance of Eel (Anguilla bicolor) maintened in containers of
different colors. Growth is the main driver in increasing the
profitability of aquaculture. In addition to maintenance
management the color of the container is also a factor
supporting the growth of eels. This study aims to determine the
effect of the color of different rearing containers on the growth
and appetite response of eel. The test fish used were elver stage
eels with an average weight (129 ±131g). The method used is an
experiment with two treatments they are grey and green. The
test fish were placed in a container measuring 19x4 m2 and a
water level of 1m with a stocking density of 1100 individuals
each, 30 days of rearing. The variables observed were growth
performance including SR (Survival Rate), ADG (Average Daily
Growth), FCR (Food Conversion Ratio), SGR (Specific Growth
Rate). The results obtained indicated that there was a significant
difference in the average growth of fish reared in grey and green
containers. Grey container treatment was proven to get higher
yields with average final weight values (192.4 ± 4.5 g), FCR (1.01
± 0.02), ADG (2.01g/day ± 0.06), SGR (1 .25%BW/day±0.02).
Based on the results of the study it can be concluded that there
is a significant difference in the growth of eels reared in ash and
green containers. The color of the ash container proved to be
better in supporting growth performance.
